In addition to presenting turbidity data, we related turbidity data to Secchi depths on the basis of Davies-Colley and Smith (2001), as hydrophyte
light limitations have been reported in relation to Secchi depth rather than turbidity (i.e., nephelometric turbidity units [NTUs]).
The protected waterfowl habitats are composed of open water, hydrophyte
, helophyte, open grass and mire scrub sub-wetlands in the investigated lake and its riparian zone.
Eutrophication is a phenomenon, in which the excess trophic substances (i.e., nitrogen and phosphorus) in lakes, reservoirs, estuaries, rivers, and certain coastal waters cause a great increase in algae and a decrease in dissolved oxygen, thus, leading to serious death of a lot of fishes and other hydrophytes
. A lot of freshwater water bodies have occurred eutrophication in the 1990s , and it was the first time for eutrophication began to become the major pollution problem of lakes and reservoirs in most countries such as Europe and North America.
Plant that grows in water and has the ability to extract oxygen from water.
Mitochondrial ultrastructure in roots of mesophyte and hydrophyte
at anoxia and after glucose feeding.
Several recent studies have been published on the biota of the Multiple-Use Reserve Martin Garcia Island--g., hydrophyte
plants (Lahitte and Hurrell, 1996), vertebrates (Juarez, 1995; Lahitte et al., 1995; Lahitte and Hurrell, 1998), the platyhelminth Temnocephala (Damborenea et al., 1997), aquatic oligochaetes (Armendariz et al., 2000; Armendariz and Cesar, 2001), Hirudinea (Cesar et al., 2009), aquatic and semiaquatic insects (Fernandez and Lopez Ruf, 1999), ostracod crustaceans (Cesar et al., 2001; Cesar and Liberto, 2008), aquatic mollusks (Rumi et al., 1996; Rumi et al., 2004; Martin and Negrete, 2006; Rumi et al., 2007; Martin, 2008), and terrestrial mollusks (Martin et al., 2009).
This is supported by Gorenflot  who mentioned that aquatic (hydrophyte
) plants have this characteristic feature.
The biological types are: C chamaephyte, G geophyte, H hemicryptophyte, Hy hydrophyte
, P phanerophyte, T therophyte.
In the current study the number of hydrophyte
and helophyte plant macroremains in both lakes decreased below 2.5 m depth (Figs 3 and 4).
Diversity of aquatic macrophytes in the Pantanal varies from the smallest (Wolffia brasiliensis Wedd.) to the largest hydrophyte
, Victoria amazonica (Poepp.) Sowerby.
In China, crops, wild plants, tropical plants, alpine plants, halophytes, xerophyte, hydrophyte
, geophyte, parasitic plants, are all found to be mycorrhizal.
